Domain Filtering

Each email address consists of two parts: the username (the part before the @) and the

domain (the part after the @). Some email clients allow their users to filter incoming

emails based on the domain of their origin addresses. For example, if an email is received

from test@example.com and a filter is set for example.com, the received email will

not be shown in the client.

You are to implement a rudimentary version of this feature. You will be given N email

addresses. You will need to count the number of emails that will be filtered out given a

string M, the email domain you will be filtering out.

Format Input

The first line contains a single integer N. The next N lines will contain a string Oi

, the

origin address of the i-th email. The final line will contain M, the email domain to be

filtered out.

Format Output

Output a single integer X, the number of emails that will be filtered out.

Constraints
